Study of palm oil additions with different concentrations during the adaptation phase for increasing the erythromycin production of Saccharopolyspora erthrea in shaken cultures resulted that the best erythromycin production was given by the addition of 3 percent plam oil. In the fermenter scale, addition of 3 percent palm oil during the adaptation phase yielded the erythromycin-production incre…
Using the wet granulation method, the granules are prepared by adding the granulating liquid to the powder mass and mixed throughly. A rough way of determining the end point during the granulation process is to press a portion of mass in the palm of the hand. Three binders are starch, gelatin and Carboxy Methyl Cellulose (CMC) had been studied as wetting granulation liquid. The end point of gra…
Twenty eight newborn mice (Mus musculus) consist of 14 males and 14 females have been treated with benzo(a) pyrene (BP) which were dissolved in dimethylsulfoxide (DMSO) solution. The lung tumour induction has been done by intraperitoneally injection of the solution at the first day of age using doses of 0.2 umol BO/0.025 cc DMSO, 8th day of age using doses of 0.4 umol BP/0.025 cc DMSO, and 15th…
Plant phenols have been reported to have inhibitory effects on glutathions S-transferase (GST) activity when 1-chloro 2,4-dinitrobenzene (CDNB) is used as a work was aimed to study on the effects of curcumin and its analogues on liver GST activity of phenobarbital and Betha-naptoflavone-treated rats. The product of the inhibition of GST-activity on the conjugation reaction between glatathione a…
The renin-angiotensin system, a complex biological system which is well known in the regulation of blood pressure has indeed multiple interaction with other regulatory system. Recently, several findings have also pointed to a possible involvement of this system in male reproductive function. High amounts of angiotensin converting enzyme (ACE), the main regulatory enzyme of this system, do not o…
